I am working on geochart.Is there any example showing how to mark a place,given only its name? I have done the same with geocoordinates,and with city names,country names with pure javascript
It depends on if Google knows where your place names are. For instance, this code will create a map with no problem of all the locations stated. Give it a try with your data and see if it plots:
function drawVisualization() {
var data = google.visualization.arrayToDataTable([
['Place', 'Popularity'],
['Statue of Liberty', 200],
['Eiffel Tower', 300],
['Big Ben', 400],
['Tokyo Tower', 500],
['Great Pyramids', 600],
['Gobi Desert', 700]
]);
var geochart = new google.visualization.GeoChart(
document.getElementById('visualization'));
geochart.draw(data, {width: 556, height: 347, displayMode: 'markers'});
}
While it looks like the Statue of Liberty didn't plot, it's on there, it's just small and pinkish

I would like to make a google chart that highlights different regions continents, or countries based on a particular grouping.
The problem is I can't figure the best way to show both continents and countries.
For instance, I'd like to have two highlighted entries: Europe and Japan.
I can use the below JS code to attempt this:
google.load('visualization', '1', {'packages': ['geochart']});
google.setOnLoadCallback(drawVisualization);
function drawVisualization() {
var data = google.visualization.arrayToDataTable([
['Region', 'Label', {role: 'tooltip', p:{html:true}}],
['150', 1, 'Europe'],
['Japan', 2, 'Japan']
]);
var options = {
resolution: 'continents',
}
var geochart = new google.visualization.GeoChart(
document.getElementById('visualization'));
geochart.draw(data, options);
};
The above code partly works- Europe is properly highlighted and labelled. However, because resolution is set to 'continents' Japan does not get highlighted. If I set resolution to 'countries' the opposite problem occurs.
So the real question:
Is there a way to highlight both Europe and Japan individually with one array entry each, or do I have to put every single European country in the list to also have Japan highlighted?
yes, you would need to put every single European country in the list to also have Japan highlighted
another option might be to draw two charts, one on top of the other,
using the following config options to allow the bottom one to show thru.
backgroundColor: 'transparent',
datalessRegionColor: 'transparent',
however, this would suppress the tooltip on the bottom chart.
see following working snippet for an example...
google.charts.load('current', {packages:['geochart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data1 = google.visualization.arrayToDataTable([
['Region', 'Label', {role: 'tooltip', p:{html:true}}],
['150', 1, 'Europe']
]);
var options1 = {
backgroundColor: 'transparent',
datalessRegionColor: 'transparent',
resolution: 'continents'
}
var geochart1 = new google.visualization.GeoChart(
document.getElementById('visualization1')
);
geochart1.draw(data1, options1);
var data2 = google.visualization.arrayToDataTable([
['Region', 'Label', {role: 'tooltip', p:{html:true}}],
['Japan', 2, 'Japan']
]);
var options2 = {
backgroundColor: 'transparent',
datalessRegionColor: 'transparent',
resolution: 'countries'
}
var geochart2 = new google.visualization.GeoChart(
document.getElementById('visualization2')
);
geochart2.draw(data2, options2);
}
.geo {
left: 0px;
position: absolute;
top: 0px;
width: 100%;
}
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div class="geo" id="visualization1"></div>
<div class="geo" id="visualization2"></div>
note: jsapi should no longer be used to load the charts library,
according to the release notes...
The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. The last update, for security purposes, was with a pre-release of v45. Please use the new gstatic loader.js from now on.
this will only change the load statement, see above snippet...
I am using Google Charts in my project where I get data from the controller as in Model Attribute. But when I see the Line Chart the x-axis comes in a reverse order.
Here's what I did:
var data4 = new google.visualization.DataTable();
data4.addColumn('string', 'Date');
data4.addColumn('number','Balance');
<c:forEach var="details" items="${details}">
data4.addRow(["${details.date}", ${details.amount}]);
</c:forEach>
var options4 = {
width: 600,
height: 400,
title: 'Amount',
hAxis: { titleTextStyle: {color: '#333'}, direction:-1, slantedText:true, slantedTextAngle:45},
vAxis: {minValue: 1000},
};`
var chart4 = new google.visualization.LineChart(document.getElementById('chart4'));
chart4.draw(data4, options4);
I get date in x-axis but in the reverse order in which it is added in the rows. I think adding of rows is like adding at the start not appending, How do I make it in the right order?
Can anyone help me.
Thanks in advance.
Ok, so I'm really hoping someone can help me get started, I have been able to plot pies and timelines from my google analytics data via api with google visualization. I now want to extract the data from google analytics of visits and plot a geomap. This is the geomap sample code which works
google.load('visualization', '1', {packages: ['geochart']});
function drawVisualization() {
var data = google.visualization.arrayToDataTable([
['Country', 'Popularity'],
['Germany', 200],
['United States', 300],
['Brazil', 400],
['Canada', 500],
['France', 600],
['RU', 700],
['South Africa', 800]
]);
var geochart = new google.visualization.GeoChart(
document.getElementById('visualization'));
geochart.draw(data, {width: 556, height: 347});
}
google.setOnLoadCallback(drawVisualization);
but of course I want to get the var 'data' from my google analytics api into such an array and plot say the top 10 popular countries based on pageviews from the last 30 days?
I believe the following query will give me what I want
dimensions=ga:country
metrics=ga:visits
sort=-ga:visits
How do I get this into the proper format for the data variable to plot this geomap? If you can help me rewrite the var data so that it works, I could be the happiest man alive.
Thanks in advance
This function should take the data returned by Google Analytics, input it into a DataTable, and draw a GeoChart of the top 10 countries by visit count:
function drawChart(results) {
var entries = results.feed.getEntries();
var data = new google.visualization.DataTable();
data.addColumn('string', 'Country');
data.addColumn('number', 'Visits');
for (var i = 0; i < entries.length; i++) {
data.addRow([entries.getValueOf('ga:country'), parseInt(entries.getValueOf('ga:visits'))]);
}
// sort by visits, descending
var sortedRows = data.getSortedRows([{column: 1, desc: true}]);
// remove all elements after the 10th
while (sortedRows.length > 10) {
sortedRows.splice(10, 1);
}
var view = new google.visualization.DataView(data);
view.setRows(sortedRows);
var geochart = new google.visualization.GeoChart(document.getElementById('visualization'));
// draw the chart using the view
geochart.draw(view, {width: 556, height: 347});
}
You should look into using the new Google Analytics SuperProxy, it simplifies the process of getting api queries into the charts api, there are still a few bugs but very simple to setup, the youtibe video on the link below will take you through the full process. https://developers.google.com/analytics/solutions/google-analytics-super-proxy
I'm wondering if it's possible to display a kind of data table in GEO Charts. I have this code:
google.load('visualization', '1', {'packages': ['geochart']});
google.setOnLoadCallback(drawMarkersMap);
function drawMarkersMap() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Country');
data.addColumn('number', 'Count');
data.addRow(["AT",141]);
data.addRow(["BE",8]);
data.addRow(["CH",42]);
data.addRow(["DE",98]);
data.addRow(["ES",942]);
data.addRow(["GR",30]);
data.addRow(["HQ",104]);
data.addRow(["HU",30]);
data.addRow(["LU",10]);
data.addRow(["NL",153]);
data.addRow(["PL",53]);
data.addRow(["PT",102]);
data.addRow(["RU",266]);
data.addRow(["SE",13]);
data.addRow(["TR",228]);
var options = {
displayMode: 'regions',
region: '150',
colorAxis: {colors: ['#ffa3b5', 'red']},
tooltip: { textStyle: { fontName: '"Verdana"', fontSize: 14 } },
legend: {textStyle: {color: 'black', fontSize: 10}},
keepAspectRatio: false,
height: 300,
width: 550
};
var chart = new google.visualization.GeoChart(document.getElementById('chart_div_02'));
chart.draw(data, options);
}
As I have some special countries (like HQ) and Turkey (that is not in region 150), I would like to a datatable or legend to the geochart.
Is this possible or do I have to make a table charts and put it somewhere else on the website?
Cheers & Thx in Advance

You cannot add a dataTable to the geoChart using the native Google Visualization API. A GeoChart is a GeoChart and a DataTable is a DataTable. However, you can create a linked GeoChart and DataTable on the same page using the same data taking advantage of the Dashboard controls and chartwrappers.
If you get fancy with your CSS, you can even hover the <div> with the table over the GeoChart, or otherwise find a way to make it look like they are the same chart.
I have a basic google chart:-
function drawVisualization() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Year', 'Austria', 'Belgium', 'Czech Republic'],
['2006', 1600652, 4604684, 940478],
['2007', 1968113, 4013653, 1037079],
['2008', 1901067, 6792087, 1037327]
]);
// Create and draw the visualization.
new google.visualization.ColumnChart(document.getElementById('visualization')).
draw(data,
{title:"Yearly Coffee Consumption by Country",
width:600, height:400,
hAxis: {title: "Year"}}
);
}
I want to be able to specify the border color and width etc.
Can you tell me how to use the API commands:-
backgroundColor.stroke,
backgroundColor.strokeWidth,
i.e How do I add these API calls.
Thanks
You can send the settings for both the stroke color and strokeWidth with the rest of you options, similar to how you've specified the title for the hAxis:
backgroundColor: {
stroke: '#000',
strokeWidth: '2'
}
That would give the chart a black 2pixel border, demo on jsfiddle.
